When you're starting any kind of garden, you will need to remove the existing vegetation in the area. Some common methods you may read about are digging, tilling, smothering, and applying herbicides...

Some seeds prefer to be sown outside directly into the ground, rather than being started indoors.
There are two different methods you can use when you’re directly sowing seeds into the garden: the hill method, and the trough method. The method you use will depend on what type of seed you’re sowing. Check the back of your seed packet if you’re not sure which method to use.
